What mount is this?

I am about to purchase a mount listed online. The owner lists it as an HEQ-5. To me it looks like my manual CG-5. Before I pull the trigger, can anyone let me know for sure if it is an HEQ-5 or just the smaller EQ-5? Thanks.

The CW nut is more typical of the Jinghua/Bosma mount. Same castings as LXD75. The tripod is not original, looks like a CG-5. Best guess is that it is a eBay Jinghua less the drives and on much better tripod. Value is $175-$225, mainly due to the demand for the tripod. Head without the tripod $50-75.
